nothing like? what shop manual ya lookin at? in the brake section there's a figure showing "main cylinder,
typical" - means not exactly as shown - the 55 manual doesn't show the yoke [fig.4], 57 does [fig.6], maybe the 56 manual is the same as the 55, but all TaskForce master cyls look just like what you've pictured
and welcome to the garage Fred!!
